OK, I have just done another test and here are my findings. TSM 4.2.2.12 running on a Solaris E250, 400Mhz, 1GB, 50GB backuppool on RAID5 array, 8500MB DB and LOG on separate internal disks (TSM mirrored).
I just backed up a 100Mb file via a client on the same machine as the server. Data transfer rate 1.5MB/s. Terrible. File was on the same RAID 5 array as the backuppool. I then restored that very same file to the very same location and got a transfer speed of no less than 51MB/s. Much better! So, could the problem lie with my backuppool for some reason, and if so, how would I know. We do have caching turned on if that makes any difference. Any ideas on this one?
